Redmine

Hi all,
I'm using redmine in configuration which described in the topic, once I have setup fetching email function, I can recieve mails and issues can be created automatically, but there is no subject ot the issue ("(no subject)") and the body of issue contains just something like below message. It seems, that somethings wrong with settings of input message format in redmine, but I can't find out where should I change it.
Can someone explain what's wrong ?

Thank you in advance.
